Nintendo sold 510,000 Wii U consoles compared with just 160,000 in the same quarter last year, when its full-year sales also fell well short of a target of 9 million. Cumulative sales of the Wii U, released in late 2012, totalled 6.68 million at end-June, well short of 8.7 million for the Sony Corp PlayStation 4 which was released a year later.
